JSA JIS H 8686-1

Abstract

This Standard specifies a visual method for determining the image clarity of anodic oxidation coatings (hereafter referred to as "coatings") on aluminium and aluminium alloy products with flat surfaces (hereafter referred to as "products"), using a chart scale and a lightness scale, which are defined. <br>NOTE 1 Visual determination of image clarity has two methods: the visual method and the instrumental method. This Standard specifies the former test method. <br>NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows. <br>ISO 10215: 2010 <em>Anodizing of aluminium and its alloys-Visual determination of image clarity of anodic oxidation coatings-Chart scale method</em> (MOD) <br>The symbols which denote the degree of correspondence in the contents between the relevant International Standard and <strong>JIS</strong> are IDT (identical), MOD (modified), and NEQ (not equivalent) according to <strong>ISO/ lEC Guide 21-1.</strong>
